If you placed a rubber baloon (not blown up but sealed) containing water into a pressurised steel vessel with liquid in the bottom half , would the `baloon` be affected by changes in the pressure, ie from vacuum to positive pressure.Would it change shape and would there be any pressure change within the baloon? Your help would be appreciated.

obtain the heat flow equation(1.3) as follows: the quantity of heat Q flowing across a surface is proportional to the normal component of \
the (negative) temperature gradient, (-\[Del]T).n
compare chapter 6 equation (10.4) and apply the discussion of flow \
of water given there to the flow of heat, thus show that the rate of \
gain of heat per unit volume per unit time is proportional to \[Del].\
\[Del]T . But
\[PartialD]T/\[PartialD]t is proportional to this gain in heat ; thus \
show that T satisfies (1.3

The average depth of the Pacific Ocean is 4300 meters. What is the pressure of the water at this depth? (Ignore the air pressure on the ocean's surface.)

A spherical balloon is filled with helium atoms (Note: 1 atm = 101.3 kPa).
(i)
What is the total translational KE of the atoms if the balloon has a diameter 36.0 cm at 6.0 °C and the pressure inside the balloon is 121.6 kPa?

(ii)The above balloon was filled from a cylinder of volume 0.4 m3 containing helium gas of 190.0 atm and at the same temperature as in the balloon in (i). How many of the balloons in (i) can the cylinder inflate?

(B)A chilly bin has walls 3.40 cm thick and the total area of the walls is 0.700 m2. The chilly bin is loaded with 4.00 kg of ice at 0.00 °C and stood on a rack so that its entire surface is in contact with the air. The temperature on the outside of the chilly bin is 35.0 °C. If the chilly bin is made of styrofoam (kstyrofoam = 0.0100 J s–1 m–1 °C–1), how many hours will it take to melt all of the ice?
(Note: Lfwater = 3.35 × 105 J kg–1)

at what temperatures kelvin and fahrenheit readings have the same numerical value?

The density of gasoline is 730 kg/m3 at 0C.
How many extra kilograms of gasoline are
obtained when thirteen gallons of gasoline are
bought at 0C rather than at 25C (tempera-
ture at the filling station)? One gallon of gaso-
line occupies 0.0038 m3 and gasoline’s volume
expansion coefficient is 0.00096(C)−1.
Answer in units of kg

a small oxygen cylinder at 300k and 10 bar is being filled from a larger tank which is at 300k and 100 bar, constant throughout the process. calculate the final temperature in the small cylinder when the pressure reaches 80 bar a) assuming that o2 is an ideal gas with cv=5r/2 and b)using accurate thermodynamic data for o2
